My stupid Galaxy CORE Prime phone keeps saying it's running out of memory. I have transferred every app, photo and video to the SD card. It STILL says I am low on memory. Under "Miscellaneous Files" it says I have 4.40GB of memory used. However when I open that tab, it doesn't add up to nearly the 4 gig it says I'm using so I have no clue what to delete. Everything is barely KB or even just Bytes. WTF?
